Abstract

Lobjectif de cette invention est de proposer un procédé très pratique pour éviter ou réduire grandement la dégradation des équipements MT et HT, dans les sites exposés à lhumidité et à la pollution. Les postes des usines où centrales électriques que ce soit dintérieurs où dextérieurs intègrent en général, des dispositions spécifiques de protection contre la pollution et lhumidité et une ventilation adaptée, attestés mais restent insuffisantes ce qui provoque des dégradations et des couts de maintenances très élevés. Dans cet objectif notre invention propose un système novateur de refroidissement et d'isolation pour les circuits de moyenne et haute tension, conçu pour contrer le phénomène d'amorçage, par utilisation dune combinaison d'eau et de CO2. Ce système a la capacité de réduire et même déliminer considérablement l'humidité du compartiment d'amorçage, créant ainsi un environnement sec et isolé. Cela permet de prévenir les courts-circuits et d'assurer la stabilité des réseaux électriques, améliorant ainsi leur fiabilité et leur sécurité.The objective of this invention is to provide a highly practical method for preventing or significantly reducing the degradation of medium and high voltage equipment in sites exposed to humidity and pollution. Substations in factories or power plants, whether indoors or outdoors, generally incorporate specific measures for protection against pollution and humidity, as well as appropriate ventilation, which are documented but remain insufficient, leading to degradation and very high maintenance costs. To address this, our invention proposes an innovative cooling and insulation system for medium and high voltage circuits, designed to counteract arcing through the use of a combination of water and CO2. This system has the capacity to reduce and even significantly eliminate humidity in the arcing compartment, thus creating a dry and insulated environment. This helps prevent short circuits and ensures the stability of electrical networks, thereby improving their reliability and safety.
